IMPROVEMENT IN INSULATORB.

lhe Schedule referred to in these Letters Patent and making part of the same.

To all to whom -these presents may come Be it known that Lhmsxpm Soon, of the city.

1 igurc'2 is a side view of the'insulawr proper, also showing a transverse section of the collar by which he insulator is held in position.

To enable othersskilled in the art to which my invention relates, to construct and use the same, I will here more fully and accurately describe its construction and operation.

The novel features of this device are two, viz, the peculiarly-shaped slot in the glass, through which the electrical conductor" passes, and the ribs on the exterior surface of the insulator, in connection with the slottedcollar.

The advantages secured by my invention are perfeet insulation, simplicity of construction, being made of but two pieces, ease and facility of adjustmentand removal, dumhility, and its cheapness. Its general adaptation to all uses where the insulation of a rodor wire is desired, as of telegraph-wires and lightningrods, is one of its peculiar and most valuable features.

My device consists of two pieces, the insulating piece, which may be made of glass or any other nonconducting material, and shown in both figs. 1 and 2, is provided with a flange, G, fig. 2, by which it is held to its proper location. It also has two or more ribs, I I, figs. 1 and 2, attached longitudinally to the body of the insulator, and which, in adjustment, pass through and are received by the slots E E. fie. 1. of the collar B B, figs. 1 and 2.

The slot F, fig. 1, consists simply of a longitudinal slot opening into and in connection with a transverse pert 'ation, beneath or behind it, in which the rod or wire 1 cobfiped.

The anispl this transverse perforation is made on a line at'an angle with the faces of the slot, thereby forming what may be termed two jaws, C O, figs. 1 and 2, which grasp add hold the conductor when the insulator is adjusted in proper position, as shown in fig. 1, A Iepl8-Sentillg.ijil\;0d.

The ribs I I and slots BE, in the collar B, are for the purpose of preventing the insulator from rotating in the collar and releasing the rod.

' This form of construction -admits of the insulator .heing attached to or removed from a lightning-rod. telegraph-wire, &c., without the use of auxiliary wires or analogous devices, and without cutting or breaking the connection of the rod or wire, or detaching it from its position. To attach it, all that is requisite to be done is to slip the collar over the insulator, let the rod or wire into the slot 1" of the same, revolve the whole around the rod until the collar is brought to its proper sea-t, then a partial revolution of the collar on its seat around the axis of the insulator brings the jaws O (1 into position, each one grasping and enclosing one side of the rod, thereby confining it -in position. The whole is then firmly secured in place by means of the screws or' spikes I) I) of the collar B. This collar may be constructed with any desired number of slots, so that its position on its scat may be changed to accommodate the screw-holes.

\Vhat I claim in this invention as new, and desire to secure by Letters Patent, is-.-

The combination of the insulator, provided with the slot F, jaws O (J, and ribs I I, with the slotted collar B, in the manner aud'for the purpose as set forth.

\Vitness my hand, at Brooklyn, New York, this 22d (lay of J unc, A. D. 1869.
